SHADE AND CHIMNEY HOLDER FOR CAR-LAMPS.

SPECIFICATION forming part of Letters Patent No. 269,587, dated December 16, 1882,

Application filed July 9, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOHN KIRBY, Jr., a resident of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, haveinvented a new and Improved Shade and Chimney Holder for Gar-Lamps; and I do hereby declare the following to be a clear and exact description of the same, sut'ficient to enable others skilled in the art to which my in vention appertains to make and use it, refer ence being had to the accompanying drawings, forming part of this specification, wherein- Figure 1 is a perspective view of a shade of acenter-lamp suspended in a holder adapted to be attached toarigid support from above. Fig. 2 is a central vertical section of the shade-supporter and the shade-supporter holder attached to a rigid support on the side, as shown at A. Fig. 3 is a sectional view of the supporter and holder, showing the application of a lamp-chimney. Fig. 4 is a plan view of the shade-supporter, showing the position of the chimneyholders when the chimney is removed.

Similar letters of reference denote the same parts in the several figures of the drawings.

, Shades for center and bracket lamps, especially those used in railroad-cars, have been suspended above the lamps in a variety of ways, among which the use of springs and set-screws are the most prominent; The lamps are usually arranged around the neck of the shade in some way; butas they hold itwith a yielding grasp the sudden jars of the car frequently mainly to avoid these defects by suspending V the shade from the inside, where the strain due to the motion of the cars can be resisted by the strongest part of the shade.

The invention also consists in the construction and application to the shade-supporterof an elastic holder for sustaining and stcadying the lampchimney.

In the accompanying drawings, A represents the ring or support by which the parts are attached to a bracket, the arms of acenter-lamp, the ceiling ofa car, or other suitable part from which the shade is to be suspended.

B is the shade or reflector, of any suitable material, of the ordinary form.

G is the shade-supporter, preferably made in the form of a cylindenwith a flaring lower end placed within the shade, so that it shall project upward through the neck thereof. The supporter is by preference made of sheet-brass, with a screw-thread spun around its projecting upper end, as shown in the drawings, to enter a corresponding screw-thread spun in a sheet-brass supporter-holder, D, fastened withina rigid support, A. The supporter-holder may be formed with a flange, E, at its lower edge to fit upon and over the edge of the shadeneck, and when the supporteris screwed tightly into the holder the shade will be clamped between the supporter-holder orits flange and the flaring end of the shade-supporter, the latter sustainingaweight of the shade below the neck andformingawidebearing-snrfaceagainst the body of the shade, where it is the strongest and best able to resist lateral strains and jars. The purpose of this flange E is to resist the upward pressure of the shade when the shadesupporterisscrewed up. Thesameefiect would be obtained by dropping a resisting edge or points from the rigid support of the shade-supporter holder orto meet the outside surface of the shade. The body of the supporter fits within the neck of the shade, and, together with the holder, holds the shade steadily in its place, while the flaring end of the shade-supporter, being of thin brass,'yie1ds somewhat when theshade is violently pressed againstit, and therefore takes up the shock and prevents the shade from breaking.

Instead of employing a sheet-metal holder within the rigid support A, the latteritself may have a screw-thread to receive the supporter. The shade-supporter may also be made of cast metal to fasten into the holder; but if thus made it is desirable that some kind of elastic packing be interposed between its flaring end and the shade to take up the shocks.

'Although perhaps the packing is not absolutely necessary,'neither is it absolutely necessary that the flaring end of the supporter shall be an unbroken circle, asthe bearingsurface may be composed of fingers or strips formed on or attached to the body of the supporter.

The chimney-holder may be attached to the shade-supporter described or to other shade Supporters, holders, reflectors, or other parts of a lamp to hold the chimney at or near its upper end, and is composed of two or more springs, F, bent in the form ofa loop, with their ends secured to suitable support in such position that the loops of the several wires shall extend to a center. The loops shown in the drawings are flattened to form angles with the shanks of the springs, and the latter may be coiled, if desired, near their ends to increase their elasticity; but if a number of springs are used the flattening may be dispensed with. Thesprings incline upward somewhat within the holders,so that when the chimney is placed between them they spring farther upward and then exert their tension to press the ends against the sides, as shown in Fig. 3. The wide loops are further bent or curved slightly to more completely embrace the chimney, as by means of their long bearings they serve to hold and steady the chimney upon the lamp.

Having thus described my invention, what I claim is 1. The combination of a screw-threaded shadesupport holder, made of spun metal, and a screw-threaded shadesupporter, made of spun metal, and an elastic chimney-holder attached thereto. x

2. The combination ofscrew-threaded shadesupporter 0, having flaring lower end, pro vided with loop-springs F, the screw-threaded holder D, having flange E, and a suitable support, A, as set forth.

In testimony of which invention I have hereunto set my hand this 21st day of June, A.D. 1880.
